On July 28, 2015 we enabled an Early Access build system for Windows Phone 8.1 Cordova apps. Despite the reference to "Early Access," this build option is not limited to use with the Intel XDK Early Access edition; it can be used with any current version of the Intel XDK.

As of today (June 26, 2015) we have finished our migration of Intel XDK accounts to the more secure intel.com login system (the same login system you use to access this forum). You will see a new login screen when providing your userid and password to the Intel XDK, and to App Preview. This is the intel.com login system you are seeing. Other than the change to a new login screen, there will be no difference for the majority of Intel XDK users.

If you push the green BUILD button after uploading your app and nothing happens (or you see the "build spinner" appear and then quickly disappear) you may have a project GUID conflict. This can be caused for a variety of reasons:

you own multiple accounts that have projects with the same name

you have multiple projects (with different names) that were copied from the same original project
